A while back I got a 9600/233, and it mostly worked pretty well (honestly I only bought it because it was $10 and had a G3 upgrade in it). However one day I plugged it in and *pop*. Power supply's out. Inrush probably killed something.
I checked it and the fuse is fine, nothing is on fire or visibly damaged, primary power (roughly 300VDC) is going through from the power input board to the other board, but there's no 5VSB voltage being generated so it can't turn on. I think a power transistor or diode died in the standby/soft power circuit but in situ my DMM doesn't show anything as obviously faulty, just that power stops at some point on the power input board. Is anybody familiar with these or have a schematic available? I didn't see anything suitable in search, either here or on the internet at large.
